I just go to the dollar store and get a green arts wire and spool of green twine. If you take the time in the early steps be gentle and use your fingernail to pinch in on it and really bend it right over it will almost horizontal with the pot. I can not stress enough take your time and go slow when you bend it. I'm always having to tape and wire one back together lol. Once its almost horizontal I bend a ? at each end of a wire, hook one end over the branch and stuff the other in the dirt. The ? helps hold it in the dirt. This will only be a week or 2. Once they reach the edge of the pot I just poke holes either throught the lip of plastic pot, or poke a hole near top of fabric pot; and use the twine to tie it down after that through the rest of the grow. In my 5gal pots I flip to 12/12 at about 14" and finish with a 36" tall manifold; I find this a little tall for my lights and get a lot of larf at the bottom 3rd.
Sorry for the novel, I love manifolding lol. hope it helps. I'm on a different PC but I will try to get a few pix up mine if it'll help
